Munguva yekugadzirwa kwearc simbi mapaipi, tembiricha inofanirwa kudzorwa zvakanyanya kuti ive nechokwadi chekuvimbika kweiyo welding. Kana tembiricha yakadzikira, iyo welding chinzvimbo inogona kusasvika kune tembiricha inodiwa pawelding. Kana simbi zhinji ichiri kusimba, zvinonetsa kuti simbi dziri kumativi ese dzipindire dzichipindana dzichibatana. Panguva iyoyo, apo tembiricha yakanga yakanyanyisa, pakanga pane simbi yakawanda munzvimbo yakanyunguduka panzvimbo yewelding. Magadzirirwo ezvikamu izvi aive akapfava zvakanyanya uye aine kuyerera kunoenderana, uye panogona kunge paine madonhwe akanyunguduka. Kana simbi yakadaro ichidonha, Ikoko hakunawo simbi yakakwana kupinda mumwe. Uye panguva yewelding, pachave nekumwe kusaenzana uye welding seams kuita maburi akanyungudutswa.

Yakadzika arc simbi mapaipi anogona kushandiswa pakufambisa kwemvura: kugovera mvura uye kudhonza. Zvekutakura gasi: marasha gasi, chiutsi, liquefied petroleum gasi. Nezvinangwa zvekugadzirisa: kusungirira mapaipi, mabhiriji; mapaipi ezvidhori, migwagwa, zvivakwa zvekuvaka, nezvimwewo. Akanyura arc simbi pombi mapaipi esimbi anotenderedzwa anogadzirwa neshinda yesimbi coils semidziyo yakabikwa, yakadhindwa patembiricha yakajairwa, uye inokwenenzverwa neotomatiki-waya mbiri-mativi akanyudza arc welding tekinoroji. . Musoro nemuswe wesimbi tambo zvakabatanidzwa butt-ichishandisa single-waya kana mbiri-waya yakanyudzwa arc welding. Mushure mekukungurutswa mupombi yesimbi, otomatiki yakanyura arc welding inoshandiswa kugadzirisa welding. Kushandisa ekunze kutonga kana mukati kudzora roller kuumba. Welding wemukati nekunze anoshandisa emagetsi welding michina ye-single-waya kana mbiri-waya yakanyudzwa arc welding kuti iwane yakagadzikana welding zvirevo.

Ndedzipi ongororo dzinofanirwa kunyudzwa arc simbi pombi dzinoda kuitwa mushure mekugadzirwa?
(1) Hydraulic pressure test: Mapombi esimbi akawedzerwa anoongororwa imwe neimwe pamushini we hydraulic pressure yekuyedza kuti ive nechokwadi chekuti pombi dzesimbi dzinosangana nedzvinyiriro yebvunzo inodiwa nechiyero. Muchina wacho une otomatiki kurekodha uye kuchengetedza mabasa;
(2) Kuwedzera kwedhayamita: Hurefu hwose hwepipe yesimbi yakanyungudutswa yearc inowedzerwa kuti ivandudze kurongeka kwepaipi yesimbi uye kunatsiridza kugoverwa kwekunetseka mukati mepombi yesimbi;
(3) X-ray kuongorora II: X-ray maindasitiri terevhizheni kuongorora uye pombi kupera weld mapikicha anoitwa pamusoro simbi pombi pashure dhayamita kuwedzera uye hydraulic kumanikidzwa bvunzo;
(4) Magnetic particle inspection yepombi inopera: Kuongorora uku kunoitwa kuti uone kukanganisa kwepombi kupera;
(5) X-ray yekuongorora I: X-ray indasitiri yeterevhizheni kuongororwa kwemukati nekunze welds, uchishandisa mufananidzo wekugadzirisa hurongwa kuti ive nechokwadi chekunzwa kwekukanganisa kwekuona;
(6) Ongorora mukati uye kunze welds ye spiral simbi pombi uye zvigadziko pamativi ese maviri e welds;
(7) Sonic inspection II: Ita sonic inspection zvakare imwe neimwe kutarisa kukanganisa kunogona kuitika mushure mekuwedzera kwedhayamita uye hydraulic pressure yemusono wakatwasuka welded simbi mapaipi;
(8) Chamfering: Gadzira pombi kupera kwepombi yesimbi iyo yakapfuura kuongororwa kuti iwane inodiwa pombi yekupedzisira bevel size;
(9) Anti-corrosion uye coating: Inokodzera simbi pombi ichava anti-corrosion uye yakavharwa maererano nezvinodiwa nemushandisi.

Iyo yakadzika arc simbi pombi fittings uye maassemblies afanogadzirwa muchigadzirwa chekugadzira anofanirwa kupedzwa zvachose, kureva kuti, majoini ese ekushivirira akaiswa welded, majoini eflange akaiswa neakareba maplate ekutsigira, uye ese mabhaudhi eflange akapfekwa nekusimbiswa. . Kuenzanisa kwekugadzirisa kukosha kwekutsauka kwekunze kwekunze kwearc steel pipe assembly haigoni kudarika mitemo inotevera; kana chiyero chekunze chearc simbi pombi musangano wakanyura uri 3m, kutsauka kuri ± 5mm. Kana chiyero chekunze chearc simbi yepombi musangano yakanyura ichiwedzera ne1m, kukosha kwekutsauka kunogona kuwedzerwa ne ± 2mm, asi kutsauka kwese hakugone kuve kwakakura kupfuura ± 15mm.

Hand-welded assemblies ane flanged connections kana mavharuvhu achaiswa pasi pekuedzwa. Magungano ese achanyorwa maererano nepfupi pombi zvinodiwa zvemadhirowa, uye migumo yavo yekubuda ichavharwa nemahwendefa mapofu kana mapulagi. Iyo yekubuda flange pamucheto wepombi yegungano inogona kusungirirwa zvakasimba kana maburi ebhaudhi eflange akaparadzaniswa zvakaenzana. Kana iri flange yakabatana nemidziyo kana flange yakabatana nebazi flange yezvimwe zvikamu, inogona chete kuve yakashongedzwa uye yakaiswa pamagumo epombi. Inogona kuiswa chete mushure mekutakurwa kuenda kunzvimbo yekuisa uye yobva yaiswa welded zvakasimba. Mavharuvhu anofanirwawo kuiswa pagungano, uye pombi mapfupi epombi dzesuweji uye pombi dzinobuda nemhepo, kuiswa kwemidziyo, uye mamakisi ekumusoro ekuisa mabhureki anotsvedza anofanirwa kuiswa weld. Iko mukati mechikamu chepombi yakagadzirwa inofanira kucheneswa. Iyo yakanyura arc simbi pombi musangano unofanirwa kufunga nezvekureruka kwekufambisa uye kuisirwa uye kuve neinogadziriswa mhenyu yekuvhura. Inofanirawo kuva nekusimba kwakakwana kudzivirira deformation kwenguva refu.
